Losing my virginity

I am 16 and a virgin. I have been talking to this guy from work I really like. We've sent nudes to each other, so we have seen each other naked, but I haven't been ready to have sex with him - until I decided I was ready yesterday. I've asked my friends who are a little more experienced than I am, but I feel like I need advice from people other than them. I know I am ready to have sex with him, I know I am ready to give my virginity to him. But I don't know what to do. Any tips/advice? Please help a sister out 😂
